I realized one more thing: We don't want to check ->get_projid() here.
Rather we should check ->get_projid() when turning quota on in
quota_quotaon() and return -EINVAL when ->get_projid() isn't set - that way
user is early notified the fs doesn't support project quotas. Then here
in __dquot_initialize() we can just check sb_has_quota_active(sb, PRJQUOTA).
